Research Finds Home Routers fill ranks of Fast Flux Botnets

Akamai researchers discovered a large (≈14,000 host) fast-flux botnet composed largely of compromised home routers in Russia, Ukraine and Romania that is being used as resilient "bullet‑proof" hosting for malware, phishing sites and web attack tools; the network leverages constantly changing DNS domains and publicly accessible HTTP/HTTPS endpoints on consumer devices, making detection and takedown difficult and leaving domain blocking as the primary interim mitigation.
